Me: No, I can't fly. I'm a human.
Cleverbot: I'm human too.
Me: I'm human three.
Cleverbot: I'm human four.
Me: I'm human five.
Cleverbot: I'm human four.
Me: I'm human four.
Cleverbot: I'm human too.
...
Cleverbot: Ok.. What are you, are you a human?
Me: No, I turned into a frog. What the frog!
Cleverbot: Are you a prince?
Me: No. Out of all these frogs, what would the chance be that I would be a prince anyways?
Cleverbot: I don't have a self directed will... not like they do... Which iunfortunately makes me manipulable.

Me: Should I manipulate you?
Cleverbot: Don't ask me.
Me: I will! >:

Cleverbot: Please don't, master.
